what version of boost are you using? Robert Ramey Diego Molla wrote:
Hello,
I have an error that is puzzling me. I have defined serialization of several custom classes, and everything worked perfectly until we've changed to a new Linux OS and had to reinstall Boost. Now the program doesn't compile and the error given is:
error: incomplete type 'boost::serialization::extended_type_info_null<SetOfRules>' used in nested name specifier
I don't really understand why it says there is an incomplete type when there used to be no errors. The same error happens with all the classes where I've defined serialization.
The offending code for the above error message is:
void save(const SetOfRules &sor, const string &fileName) { std::ofstream fout(fileName.c_str()); boost::archive::text_oarchive oa(fout); oa << sor; // <== Here is the error fout.close(); } // save
Currently I'm using gcc version 4.0.4 20060507 (prerelease) (Debian 4.0.3-3)
Can anybody help?
